But what is coffee milk?

And why is it so popular in New England but virtually unknown elsewhere?

Here’s a little insight into the background.

What is coffee milk?

Coffee milk is created by adding coffee-flavored syrup to milk, Eli Berkowitz, CEO of Little Rhody Foods, told Fox News Digital in a phone interview.

It is similar to adding chocolate syrup or strawberry syrup to milk to make chocolate and strawberry milk.

Little Rhody Foods is a distributor of the three major coffee syrup brands: Autocrat, Coffee Time and Eclipse. This syrup is not brewed coffee, but according to the ingredients list it contains coffee extract.

“It’s a tradition in Rhode Island,” Berkowitz said. “As soon as you leave (Rhode Island) and go to New York, everyone thinks you’re talking about something else. You have no idea.”

He added: “It’s just bizarre that it’s just a Rhode Island thing.”

Berkowitz, like many people in Rhode Island, has been drinking coffee milk since he was a child.

“I think it was a way to get kids to drink more milk.”

“It was just a staple in New England for some reason. That’s how we all grew up as kids,” he said. “I’m 65 and that’s what I’ve always wanted.”

Coffee milk, Berkowitz said, doesn’t have the exact flavor profile of a regular hot cup of coffee.

“It just has a sweet taste. This is it,” he said.

Although the product contains caffeine, it varies by brand, Berkowitz noted.

Still, its superficial similarities to the drink typically consumed by older people are probably why it’s so popular with children, he said.

“I think as kids growing up, mom and dad would have a cup of coffee – (it was) like, ‘Can I have that?'” he said.

“It tastes like melted coffee ice cream!”

Instead of coffee, parents would recommend their children drink coffee milk because “it is darker in color.”

“I think it was a way to get kids to drink more milk,” Berkowitz said.

“If kids didn’t like plain milk, it was somehow sweetened with (syrup).”

On June 29, 1993, coffee milk was adopted as Rhode Island’s “state beverage,” according to the Rhode Island Secretary of State’s website.

“Coffee milk tastes best with the right ratio of Autocrat coffee syrup and milk, preferably 2%,” he said.
